Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 29021-2012 "Beam Pumping Unit in the Oil and Gas Industry" and is consistent with GB/T 29021-2012.

In addition to structural adjustments and editorial changes, the main technical changes are as follows:

---Changed the description of the rope suspension carrier (see 5.2.6, 2012 version of 5.2.6);

---Changed the contents of "Table 3" (see 5.3.1 Table 3, 4.3.2 Table 3 of the 2012 version);

---Changed the requirements for reducer gear hardness matching hardness difference (see 5.3.2.2, 6.3.4, 2012 version of 5.3.2.2, 6.3.4);

---Changed the requirements for rolling bearing life (see 5.3.4.2.2, 2012 version of 5.3.4.2.2);

---Changed the performance requirements of keys (see 5.3.4.4, 2012 version of 5.3.4.4);

---Changed the fastener performance requirements (see 5.3.4.5.1, 2012 version of 5.3.4.5.1);

---Deleted "fastening bolts" (see 5.5 of the 2012 edition);

---Delete the relevant requirements for beam processing (see 6.2.7 of the 2012 edition);

---The calculation formula for the allowable eccentric moment of the pulley has been changed (see 6.3.8, 2012 version of 6.3.8);

---The overall noise index of the beam pumping unit has been changed (see 6.5.5, 2012 version of 6.5.5);

---Changed the requirements for the donkey head clearance space of the beam pumping unit (see 6.5.10, 2012 version of 6.5.10);

---Added the requirement for the height from the bottom of the rope suspension to the bottom of the base (see 6.5.12);

---Inspection items and inspection methods for the height from the lower end of the rope suspension to the bottom of the pumping unit base have been added (see Table 18, No. 28, Table 22, No. 28) No. 18, Table 23 No. 16);

---Added the method of type test and factory inspection of "the connection strength between the rope suspension and the wire rope" and "the connection strength between the drive rope and the prefabricated head" method, the inspection methods of "conical surface of crank pin and taper sleeve" and "crank-scissor difference" have been changed; (see Table 18 No. 4, No. 5, No. 7, Serial number 23, 2012 version of Table 20 (serial number 4, serial number 5, serial number 7, serial number 24);

---Deleted the reducer gear accuracy grade inspection item (see serial number 10 of Table 20 of the 2012 edition);

---Changed the loading and running-in test time for the factory inspection of the reducer (see Table 20, Table 22 of the 2012 version);

--- Added factory inspection items for castings (see Table 23 No. 2);

---Deleted the content marked with the production license number in the nameplate [see 8.1.3b) of the 2012 version].
